UNITED STATES PATENT OFFICE f JOHN W. HSSEY, OF BOSTON, MASSACHUSETTS,ASSIGNOR TO GEORGE S. HABWOOD AND GEORGE H. QUINCY, OF SAME PLACE.

IMPROVEMENT IN MACHINERY FOR OILING WOOL IN CARDING-MACHINES.

Specification forming part of ILetters Patent No. 46,189, dated January31, 1865.

.To @ZZ whom it may concern:

Be it known that I, JOHN NV. HUSsEY, of Boston, in the county of Suffolkand State of Massachusetts,have invented certain new and usefulImprovements in Machinery for Oiling Wool 5 and I hereby declare thatthe following is a full, clear, and exact description of the same,reference being had to the accompanyin g drawing, which represents asectional elevation or diagram of the apparatus for oiling wool, towhich my said improvement is applied.

In Clissolds oiling apparatus, for which Letters Patent of the UnitedStates were issued on the 24th day of February, 1862, and reissued toHARWooD and QUINGY on the 13th day of-September, 1864, apressure-rolleris used which performs the double function of applying or conveying theoil to the wool as it is fed to the carding or other wool-preparingmachine and of iinprintingit on or disseminating it through the wool.This pressureroller is generally located over the feed-apron, in theimmediate vicinity of the top feedroller of the card, so that the fibersof wool which adhere to the oiled surface of the roller are taken oifand carried to the card bythe action of the feed-roller. Ihisarrangement of the apparatus is generally carried out on English 1n achines in which no burr-box is used; but on' most of the Americancarding-engines,i a burr-cylinder and burr-box are used, and, the latterbeing necessarily placed over the top feed-roller and feed-apron, itinterferes with the location of the pressure-roller in close proximitywith the feed-roller. In carding-machines, therefore, with which a.burr-box is combined, the pressure-roller is located at such distancefrom the feed-roller as to clear the burr-box; but the objection to thisarrangement is that thereis no mechanical means of keeping thepressure-roller clear and that the wool adhering to its surface isnecessarily discharged by a special attendant,

which is Va source of much trouble, danger, and expense. lo remedy thisI have tried would accumulate faster than it was practicableto-reciprocate the blades. Straight edgesi. e., stationaryblades-extending the whole length of the roller were also tried; butthese are liable to become clogged up. From these and other experimentsI have come to the conviction that the best way to keep the roller cleanis to bring it in contact with or in very close vicinity to a surfaceconstantly moving in a contrary direction, so that the roller shall bestripped of the fibers within a short distance of the feed-apron-ie., asfast as the fibers adhere to it-and this I have accomplished by theemployment, interposed between the top feed-roller and thepressure-roller, of an endless apron mounted upon two rollers whichrevolve in the same direction as the feed and pressure rollers, so thatthe surface of the apron in contact or nearly in contact with the feedand pressure rollers will move in opposite directions to y theirsurfaces.

'Io enable others to make and use my invention, I shall now proceed todescribe the manner in which lthe same is or may be carried into effect.

Referring to the drawing, A is the feedapron, B and (l the feed-rollers,and D the burr-box, of an ordinary carding engine, and thepressure-roller G is shown placed at a convenient distance in front ofthe burr-box. Between the pressure-roller G and the top feed-roller, B,there are two rollers, I and M, around which is passed an endless apron,lt, which is here shown to consist of slats riveted or otherwisefastened to an apron or band of leather or other material. The rollerscarrying the apron are located in such manner as that the apron touchesor nearly touches both the pressure and the feed roller, and they aregeared to revolve in the direction of the top feed-roller. By thisarrangement the apron performs,` with respect to the pressure roller,the same functions as the feed-roller in Glissolds apparatus-that is tosay, it presents a surface constantly moving in contrary direction tothe surface of the roller, keeping it constantly clean and clear of thefibers carried up from the feed-apron. On the other hand, thefeed-roller acts upon the endless band in the same way as the band onthe pressure-roller-. c., any fiber that still adheres to the bandiisremoved by the feedroller and carried to the. card.

Having thus described my invention and the manner in which the same isor may be performed, I shall state my claims as follows:

l. In carding or other Wool-preparing machinery, and in combination withthe pressure-roller of an oiling apparatus of otherwise ordinary orsuitable construction, an independent scraper, or itsequivalent, soarran ged as to keep the pressure-roller clear of the Wool adhering toits surface.

2. In combination with the pressure-roller of an apparatus for oilingwool as it is fed to JOHN NV. HUSSEY.
